Frequently asked questions

Ceven does not hold your private keys. For actions that require a signature, such as creating a listing or an offer, Ceven generates the necessary transaction data and request. You must approve these requests through your connected wallet provider. The agent prepares the payload and sends it to your wallet for a final sign off. This ensures that you maintain total custody of your assets while the agent handles the heavy lifting of monitoring and drafting the orders. Once you sign the transaction in your wallet, it is broadcast to the blockchain and OpenSea updates the listing state.
Ceven can automate the discovery and the preparation of the purchase. Use the Fulfill Listing action to get the required signatures and data. However, because OpenSea operates on decentralized blockchains, the actual movement of funds requires a wallet signature. Ceven can notify you the millisecond a target asset hits your price and provide a direct link to sign the transaction. This prevents the agent from spending your funds without a manual check while still providing the speed of an automated bot for finding undervalued assets.
OpenSea enforces strict rate limits on their API to prevent abuse. If a workflow polls collection stats too frequently, OpenSea may return a 429 error. To handle this, Ceven implements an intelligent queuing system that spaces out requests and uses exponential backoff. If you are running a high volume trading operation, we recommend using a dedicated API key from OpenSea. The agent will automatically detect the rate limit headers and slow down the execution of the workflow to ensure your API key does not get banned or throttled during critical market moves.
Yes. OpenSea supports multiple chains such as Ethereum, Polygon, and others. When using actions like Get NFT or Create Listing, you must specify the chain in the request. Ceven stores the chain metadata alongside the asset ID so the agent knows exactly where the asset lives. If you are tracking a portfolio across three different networks, the agent can aggregate all those listings into a single report and notify you when any of them receive an offer, regardless of which blockchain the asset is hosted on.
A criteria offer allows you to bid on any item in a collection that has a specific trait, such as a certain color or accessory. Ceven uses the Build Criteria Offer action to construct the merkle tree and the offer details. You can set up a workflow that says if any NFT with the trait Gold Fur appears in a collection, submit an offer for 1 ETH. The agent constantly monitors the collection and automatically submits the offer as soon as a matching asset is listed or identified as available.
Ceven uses a combination of the Get Traits and Get NFT actions to analyze a collection. The agent can pull the full list of traits and then iterate through the best listings to find assets with the lowest trait frequency. By comparing the rarity of an asset against the current floor price, Ceven can flag items that are significantly undervalued based on their rarity score. You can set up a daily report that lists the top five most undervalued rare assets currently listed on OpenSea.
Yes. Use the Cancel Order action to remove listings. This is particularly useful for portfolio rebalancing. You can create a workflow that cancels all active listings for a specific collection if the floor price jumps by more than twenty percent in one hour. This prevents you from selling your assets too cheaply during a sudden price spike. The agent identifies the order hash for every active listing you have and sends the cancellation request to OpenSea to ensure your assets are protected.
Metadata on the blockchain is static, but the marketplace view can sometimes lag. Ceven can trigger the Refresh NFT Metadata action on a schedule or based on an event. For example, if you buy a new NFT, the agent can immediately request a refresh so that the traits and images are correctly mirrored in your internal tracking system. This ensures that your portfolio view always reflects the most current state of the asset as recognized by the OpenSea servers and the underlying smart contract.
